# Worldwide Netgraph

Open `/netgraph/` from the map toolbar to see the same sanitized live feed as a stable topology diagram. Every connected node remains available; the selected time window controls visible historical links. The default is 15 minutes, and explicit window choices stay local to the browser.

Nodes are grouped by four-character Maidenhead grid squares, each two degrees of longitude by one degree of latitude. The area title shows the square code and its centre coordinates. This standard worldwide radio locator comes directly from public node coordinates: there is no country registry, geocoding service, or new backend field. These are display groups, not political boundaries or coverage predictions. See [ARRL's worldwide grid description](https://www.arrl.org/international-grid-chase-2018).

Live packets retain their hop order, protocol colours and synchronized sound. Matching packets receive bounded emphasis while a node is inspected. Area cues show LOCAL traffic or paired OUT/IN activity; DX identifies qualifying long-distance inter-area traffic. Other traffic remains visible and every visible hop keeps its musical note.

Use mouse/wheel, native touch gestures, or the zoom buttons. Reset fits the whole topology, including networks spanning continents. Finder supports Up/Down, Enter and Escape. On slower renderers, secondary decoration and compositing adapt to measured frame cost without dropping live hops or hiding topology. Reduced motion retains stable cues and fading residue.
